Was going to comment about a knife as well but you beat me to it. Though I went with Wusthof. The difference a good knife makes a huge difference for cooking.

The same applies to cookware. Don’t overpay buying a whole set is a waste. Buy the couple pots and pans you need individually and save.

I like to add a splash of cocktail bitters to soda stream water. A bit of fresh fruit and herbs is nice too.

I picked up that same Ryobi starter kit when I bought my house. I know they aren’t the top of the line, but it’s served me well for light duty household projects.
